Files of the form date_time_AR_tb_masks.fits contain the transient brightening heat map and the instantaneous 
transient brightenings masks:

The first (primary) HDU is an (nx,ny) dimensional array containing the approximately two-hour cumulative transient
brightening heat map. 
WCS information is provided in the headers to construct the coordinates of each pixel:
xn_i = CRVALn + CDELTn * (i - CRPIXn)

The second (first extension) HDU is an (nx,ny,nt) dimensional array containing the instantaneous transient 
brightenings masks. 
WCS information is provided in the headers to construct the coordinates of each pixel:
xn_i = CRVALn + CDELTn * (i - CRPIXn)

The third (second extension) HDU is an (nt) dimensional array containing the time steps of the instantaneous 
transient brightening masks, which also corresponds to the time interval of the heat map.

Files of the form date_time_AR_AARPs_1600.fits contain the AIA Active Region Patch of the corresponding active 
region and the analysis time range:

The first (primary) HDU is an (nx,ny,nt) dimensional array containing SDO/AIA 1600 A images. 
WCS information is provided in the headers to construct the coordinates of each pixel:
xn_i = CRVALn + CDELTn * (i - CRPIXn)

The second (first extension) HDU is an (nt) dimensional array containing the time steps of each AARP image 
contained in the first HDU.
--------------------------------------------------------------------------------------------------------------------
Files of the form date_time_AR_hdbscan.fits contain the transient brightening cumulative map, with each pixel
value representing the cluster it belongs to:

The first (primary) HDU is an (nx,ny) dimensional array containing the approximately two-hour cumulative transient
brightening HDBSCAN cluster map. 
WCS information is provided in the headers to construct the coordinates of each pixel:
xn_i = CRVALn + CDELTn * (i - CRPIXn)

Example code in IDL to read in both parameters:

data=readfits(path+'2011-09-06T17:00:00_AR11283_tb_masks.fits', header, ext=0) ; to read in the TB heat map

data=readfits(path+'2011-09-06T17:00:00_AR11283_tb_masks.fits', header, ext=1) ; to read in instantaneous TB masks

data=readfits(path+'2011-09-06T17:00:00_AR11283_tb_masks.fits', header, ext=2) ; to read in the time information for 
ext=0 and ext=1
